From the developer:
AutoTheory works as a filter between your MIDI controller/keyboard and your DAW, it is not a Plug-in. AutoTheory intercepts the data from your keyboard and sends up to 8 virtual midi controllers into your DAW. Setting up AutoTheory is the same as setting up multiple midi controllers inside of your DAW.
